Can someone tell me a good alternative, I don't like I tunes its too commercial you can't fart without having to sign up for something, and I don't like the way its library organises tunes etc etc.

Huh? You can disable the store? I don't have anything related to any commercial things in my iTunes :P

And I love it :P

However, back to topic, there are a few:

Songbird, Yamipod, Floola, JakPod & reTune

How do you get album info without signing up for an account?

Use GimmeSomeTune (Free). It will display album artwork for you(and it really works), and even lyrics for songs. I know, it's a third party app, but you can set it to open and close with iTunes, and it rellay doesn't take that much memory, around 13-15MB.
